To all whom it may concern: 7

Be it known that we, HARLON A. CLIFFORD and JAMns W. COBB, citizens ofthe United States, residing at Greenfield, in the county of. Franklin,invented anew and useful Anesthetic-Dispenser, of which the following isa specifi cation.

This invention relates to a'devi-ce'for use in dispensing anesthetics,one of its objects being to provide a simple and compact struc tureadapted to be attachedreadily to the cone ordinarily placed over theface of the patient, it being possible at all times readily to determinethe amount of anesthetic within the device and the amount which has beendispensed.

A further object is to provide a device of this character which may bereadily controlled by the user.

With the foregoing and other objects in view which will appear as thedescription roceeds, the invention resides in the comgination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings:

Figure 1 is an elevation of a dispenser em bodying the presentimprovements, a portion of a cone being shown engaged by the dispenser;and

Fig. 2 is a section on line 2-2 of Fig. 1.

Referring to the figures by characters of 7 reference 1 designates atube preferably of glass and which is housed within a metal jacket 2,there being a longitudinal slot within the jacket through which theglass tube 1 and the contents of said tube may be seen. Graduations maybe arranged along this slot to indicate the amount of anestheticcontained within the device.

Detachably engaging the ends of the jacket 1 is a shallow conical base 4which screws onto the lower end of the jacket 2, there being a gasket 5of any suitable material interposed in the space between the lower ofthe tube 1 and the jacket 2. a ni downward from Specification of LettersPatent. Application filed April 8, 1918. Serial No. 227,287.

the center of the base 4 and has a tapered outlet opening 7. Downwardlydiverging legs 8 extend from the base and detachably connected to thelower-portion of each of these legs is a clamping plate 9, there be inga thumb screw 10 for adjusting the plate toward orfrom-the legs. j

' A cap llis screwedonto the upper end of the jacket 2 and has ascrew-threaded opening 12 extending through the center thereof.Extending through this opening is the threadedportion of a valve stem13, the end ofthis stembeing tapered as at 14: to form a needle valveextending into the nipple 6.

' A clamp nut 14 engages the threaded por tion of the stem 13 and isadapted to bear against the head or cap 11 and a set nut 15 engages saidstem and bears against the clamp nut. A knob or head 16 is provided atthe upper end of the stem 13. By means of the head 16 the stem 13 can berotated, thus to move the needle valve toward or from its seat andregulate the outflow of liquid from the device. By tightening the nuts14 and 15, the stem 13 can be held against rotation after adjustment.

A feed opening or funnel 17 is provided A in the cap or head 11 and maybe closed by any suitable device provided for that purpose.

A gasket 18 is preferably interposed between the upper ends of the tube1 and the jacket 2 and the cap 11.

In using the device the anesthetic is placed in the dispenser throughthe feed opening after which the funnel 17 is closed. The legs 8 areattached to the marginal portion of the cone C by means of the clampingplates 9 and the valve 16 is then opened sufliciently to allow theanesthetic to discharge for indicating the e5 anesthetic dis pensedtherefrom, and a valve tithe base the container.
